I played it. This demo is very very short. But I like it and I want to see how it will be! Nice pixel art and animations. I have a small monitor and the window is very big. If you can, resize it in full screen mode. I like also the sounds and the music. Warning about the level design. This should be only a "tutorial level" but it's not so "clear". I suggest you to see this video https://www.youtube.com/watch?v=8FpigqfcvlM
